I owned an AFR 204 fretless in the 90's.
Great instrument, but the gas won.
Never seen a fretless again since then, except for a few monthes ago, but the ad disappeared after a week or two. It must have been sold quickly.
Again a great looking and sounding bass.
Rolf Spuler was also a very kind person, he gave me a B string piezo for my AFR 305, when it broke during a transport.
GLWYS,
